Use of a vacuum evaporator unit in Gilde Brauerei AG brewhouse
To Harald Wildhagen on the occasion of his 60th birthday
A flash evaporator unit has been in operation since summer 2002 in Gilde Brauerei in Hanover. The unit supplied by Ziemann was installed between whirlpool and wort cooler. On the one hand, this did not involve any interference in the “wort boiling” system. On the other hand, this is the only location assuring stripping of DMS reconstituted in the whirlpool. The objective of the installation was to significantly reduce boiling time from the previous 70 min so as to achieve technological and energy-related improvements.
The main energy user in the brewhouse is wort boiling. This has always been at the centre of attention when trying to save energy. The most important factors influencing wort boiling are shown in Fig. 1.5%.
